Shoulder trauma Flashcards
Gold standard for soft tissue injury in shoulder
Arthroscopy
Chronic rotator cuff tears xray clues
- eroded inf aspect of acromion
- norrowed acromiohumeral space
- flattended greater tuberosity
MC loc of clavical fx and what happens to peices
m/c in middle fragment- med fragment will elevate, distal fragment will go inf
-prone to non union, malunion
Prognois of clavical fx in adults
adults have increased risk of neurovascular damage and non union
bayonette deformity of clavicle
Sig displaccement + overlap of the fx ends, distal fragment typically displaced inf
M/c shoulder dislocation and its subtypes
ANT- 95%
- subglenoid
- subcoracoid
- subclavicular
- Intrathoracic
Signs of a post disloaction (3)
loss of overlap of humeral head on glenoid, will lood like its behind glenoid
light bulb sign (int rot)
rim sign- >6mm widening of GH jt
trough sign- dense vert line in med hum head
Signs of inf shoulder dislocation and complications
-due to severe hyperabduction
- stabile
- gotta asses for neurovascular injury
Associated injiries with ant shoulder disloaction (mc)
hills sachs (60%)- lesion in posteriosuperior aspect of head on lat side due tp hitting glenoid
Flap- inf glenoid can hit greater tub and tear it off
Bankart lesion- detachment of ant inf labrom from glenoid
Associated injuries with post shoulder dislocation
Reverse hill sachs- indentation of upper med part of humeral head
3 types od AC jt injuries
1- ac gets stretched 2- Ac stretched, cc stretched 3- Torn ac and cc ligs 4- clavical post 5- clavical way up
Osteolysis of clavicle
Usually distal 1-3mm of clavical affected
visible after 2-3m
Surgical neck fx of humerus presentation, tx
typical appearence after foosh of minimally displaced prox humerus involving surgical neck and some greater tub
